C Puzzle -Printf
How output from below printf was
"Hello! how is this? super
That is C! "
This is taken from A QuizCode:#include <stdio.h> int main() { int a=3, b = 5; printf(&a["Ya!Hello! how is this? %s\n"], &b["junk/super"]); printf(&a["WHAT%c%c%c %c%c %c !\n"], 1["this"], 2["beauty"],0["tool"],0["is"],3["sensitive"],4["CCCCCC"]); return 0; }

Here's a simpler example using the same principal -
Code:int a[5] = { 1, 2, 3, 4, 5 }; int i = 3; printf("%d", i[a]); /* NOT a typo */
What about this??
printf(&a["Ya!Hello! how is this? %s\n"], &b["junk/super"]);
&a["WHAT%c%c%c %c%c %c !\n"]
Before throwing strings into the question, do you understand my simpler example?

I hope this wasn't a question from anyone serious (like say a prospective employer)
If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
If at first you don't succeed, try writing your phone number on the exam paper.
